Definitions

  • the invention relates to a front jaw of a safety ski binding arranged in front of a front base plate of a ski according to the preamble of claim 1 (as described for example in FR-A-2 553 672).
  • the aim of the present invention is to provide a front jaw of the type mentioned in which, in the event of a forward inclination and in particular a frontal fall of the skier, the lateral release force is reduced in a defined manner without a power transmission having to be arranged between the base plate and the sole holder.
  • the sole tip engaged with the sole holder allows a defined downward movement in the event of a forward inclination, in particular a frontal fall of the skier, until one acting down on the sole holder and by a spring or the shoe sole itself generated force presses the stop against the inclined surface, whereby a relieving force is exerted on the sole holder in the sense that the side release can be accomplished with a lower force.
  • the stronger the movement of the sole tip is down i.e. the more intense pressure is exerted on the front part of the shoe sole from top to bottom, the longer or the further the stop on the inclined surface can shift, i.e.
  • the counterforce to the sole holder restoring force which takes effect from a certain downward movement of the sole has a constant value. The harder the tip of the sole is pressed down, the longer this counterforce remains when the side is released.
  • the downward movement of the ski boot sole is ensured in the event of a forward fall by the measures of claim 3.
  • the inclined surface is flat and extends transversely to the longitudinal direction of the ski.
  • the angle of the inclined surface must not become so steep that the projection slides down on the inclined surface without a lateral release movement. Preferred angles are through Claim 5 defined. The angle is dependent on the available force exerted downwards on the sole holder.
  • the embodiment according to claim 6 has the advantage that with a side release movement only one half of the sole holder is claimed, the other, however, is without power.
  • the embodiment according to claim 7 prevents the pushing force acting from the heel cheek over the ski boot on the front cheek exerting a lateral triggering moment on the sole holder. By slightly displacing the support points in the lateral direction relative to the tilt axes, however, defined slight spreading or closing forces can be exerted.
  • the arrangement of the inclined surface according to claim 13 is preferred, because in this way an edge which is provided at the bottom and front of the sole holder can be used as a stop for cooperation with the inclined surface fixed to the housing.
  • a corresponding inclined surface with a stop can also be provided in the upper region of the front jaw according to the invention, as defined in detail in claim 14.
  • the construction of this additional inclined surface and the additional stop can be analogous to claims 4, 5. Only for the shift of the sole holder upward force is not generated by a spring, but by the tip of the boot sole. In this way, the frictional force occurring between the sole holder and the sole tip in the event of a backward fall can be largely compensated for.
  • stops and inclined surfaces can also be exchanged kinematically within the meaning of claim 15.
  • the embodiment according to claim 16 has the advantage that the sole holder is also acted upon by the pushing force acting from behind on the front jaws with a downward force component which presses the sole holder against the top of the sole tip and, according to the invention, on the sole holder from contributes pre-tensioning force.
  • an elongated base plate 21 which extends across the top and is secured by a spring arrangement 31 on the top of the ski 22 is that if the skier leans forward due to the greater pressure exerted by the sole 14, it can move downward by a distance dependent on the pressure force exerted from above.
  • a front jaw 23 is arranged in front of the base plate 21 on the ski 22 and comprises a sole holder 16 consisting of two halves 16a, 16b and a housing 20 fastened to the ski 22.
  • the two halves 16a, 16b of the sole holder 16 are formed symmetrically to the vertical central longitudinal plane 11 of the front jaw 23, with the exception of the articulation eyelets 16a ', 16a ′ and 16b', 16b Sind, which are offset in height, to one and the same, further bolts 28 described below can be hinged.
  • the sole holder halves 16a, 16b have concave tilting surfaces 13 at the front, which are relatively narrow and extend vertically from top to bottom. These support surfaces 12 are essentially complementary to the housing-fixed support surfaces 12.
  • the tilting surfaces 13 are by a release spring 26, which is supported with its rear side on a housing-fixed abutment 20 'and with its other end via a spring preload adjusting screw 32 and a pull rod 27 on a vertically extending bolt 28 acts on which the two sole holder halves 16a and 16b are articulated by means of the articulation eyelets 16a ', 16b' or 16a ⁇ or 16b ⁇ in the middle between the two support surfaces 12, pressed forward against the support surfaces 12.
  • a lateral force F (FIG. 1) now acts on the sole 14 of the ski boot 15, for example due to a skid of the skier, the right half 16a of the sole holder 16 swings out to the right, specifically about the vertical tilt axis 17 (FIG. 1, 1a). The left half 16b of the sole holder 16 becomes weak.
  • a bias spring 24 extends vertically, for example, between the rear end portion of the tie rod 27 and the base plate 10 and biases the sole holder 16 downward in a manner explained below.
  • a flat inclined surface 19 which slopes obliquely from top to bottom and rear and which cooperates with a stop 18 formed by the lower front edge of the sole holder 16.
  • the arrangement of the inclined surface 19 is such that when the ski boot 15 (FIG. 2) is set and the skier is in a normal posture without excessive presentation of the stop 18, no force is exerted on the inclined surface 19 from above and in particular is at a small distance from the inclined surface 19.
  • the force exerted on the base plate 21 from the front part of the sole 14 increases downward, so that the latter is displaced downward against the force of the spring arrangement 31.
  • the sole of the shoe can also move downwards also tilt it down a bit around the front edge 33 of the base plate 21.
  • the upper surface of the sole 14, which engages with the sole holder 16 also moves downward, so that the sole holder 16 now under the action of the force of a prestressing spring 24 which prestresses it downward along the support surfaces 12 can slide down relative to the housing 20 until the stop 18 comes to bear on the inclined surfaces 19.
  • the shoe sole 14 is also e.g. due to a combined frontal camber in the lateral direction, the force for the lateral pivoting of the relevant half 16a or 16b of the sole holder 16 is reduced accordingly.
  • the increased friction between the base plate 21 and the shoe sole 14 due to the additional load can thus be at least largely compensated for by a reduction in the lateral release force.
  • a stop 18 ' can be provided in the middle between the tilt axes 17', which cooperates with an upper housing-fixed inclined surface 19 'in an analogous manner.
  • Front support rollers 29, which are in alignment with the tilting axes 17, are provided on the sole holder 16 and lateral support rollers 34 for the edge of the sole 14 are provided at the rear end of the obliquely outwardly extending sole holder halves 16a, 16b.
  • the support points 25 created by the front rollers 29 are in alignment with the tilt axes 17, so that the pushing force A originating from the heel jaws, not shown, has no influence on the lateral triggering behavior of the front jaw 16.
  • FIGS. 3 and 4 the same reference numbers designate corresponding components as in FIGS. 1, 1a and 2.
  • the force pressing the sole holder 16 downward is caused by an oblique drop in the axis and thus the direction of force of the release spring 26 or the pull rod 27 to the front and scored below.
  • the force exerted by the release spring 26 also has a component which runs downwards in the direction of the tilting axes and which generates part of the prestressing force for the sole holder 16 downwards.
  • the tilt axes 17 in the embodiment according to FIGS. 3, 4 are tilted somewhat with respect to the vertical in such a way that they run from top to bottom and somewhat to the front. In this way, the pushing force A originating from the heel cheek also generates part of the prestressing force acting downwards towards the inclined surface 19.
  • a step stop 30 is provided which engages with the underside of the tip of the sole 14.
  • the sole 14 When the sole 14 is moved down in the event of a frontal fall, the sole 14 itself also exerts a downward force on the sole holder 16 via the step stop 30, which force leads to a further reduction in the lateral release force via the inclined surface 19.
